Focus: Corrosion and tribological behavior


Sample holder with sample for hydrothermal corrosion.

Corrosion is the local or extensive reaction of a material or component with a surrounding medium, which leads to degradation of the material or even to is destruction.  The corrosion behaviour of materials not only contains the chemical aspects but also mechanic and micromechanic aspects like reduction of strength through pitting corrosion and acceleration of subcritic crack propagation under mechanic strain in the corrosion medium. Technical ceramics are more stable than common metallic materials. But still the corrosion behaviour of these materials varies depending on their composition.
